But my Premature ejaculation may be happens .I ejaculate over her vagina. She is 21 years old, she had take unwanted 72 within 24 hours after sex. Her normal regular period date was 8th July and duration is 4 days i.e 8th of every month. After taking unwanted 72 her bleeding start on her regular period date and ends in only 2 day. BUT she is not sure that it was her regular period or bleeding due to unwanted 72 because it end within 2 days.
